Be it known that l'. 'l.\11i. Jamin, a sub- Jeet'ofthe EmperorI ofAustria-Hungary, residing at Cleveland, 1n the county of Cuyatainnew and useful Iml'irovements in Antomobile Brakes and Jacks; and I hereby de- `clare the following tobe a full, clear,and exact description of the invention, such as will enable'otliers skilled in the art to which it pertains to make and'nse the same.

Thisinvention relates to new and useful improvements in vehicle brake`s,an'd particula'rly to a brake for automobiles.

- The object of this invention is to provide an emergency brake' for a'vehicle which can be quickly operated, which will be very eft'eei tive in stopping the motion of the vehicle andwhich willat'the 'same 'time tend tolessen the shock'of the suddenstoppage of the-'vehicle to a' greaterv extent than the brakesnow in use,

A further` object of my..` invention is to provide. a deviceof this characterA which can also be utilized as a jack for'lifting the rear portion and back-wheels of a vehicle in case itis necessary to make repairs to the ma! chineryor tires of the rear wheels.

` With these objects in `View 'my invention therefore consists in the features of construct-ion andacom'binat-ion of' parts, the preferred form'of which is illustrated in the accomticationand setforth inthe appended claims.

Referring to the accompanying drawings` Figure 1 is a. side elevation of an autoniebile showing my improved brake applied thereto. Fig. 2 is a-bottom plan of the same'. Fig'. 3 is a detail view in section of the bracket support for the brake member. Fig.

"Fig, 6 'is a section on line 6 6, Fig. 3. Fig. 7 is a figure similar to Fig. 6 showing the brake supporting shaft shifted.

Again referring'to the drawings 2 represents the body of an automobile which is 3 -and wheels 4 which are secured thereto in the usual manner. On the bottom of the body, at each side thereof is rigidlysecured Specification of Letters Patent. Application 1aed prix 11, 1911.

Serial No. 621.472.

each bracket member is provided with a pair of downwardly extending flanges l0, and in the said flanges are formed openings l1. A shaft l2 extends transversely of th'e body Q and the ends thereof extend through the said openings 11 in the said tlanges 10 am. at each end t-he shaft is provided with corrugations or longitudinally extending teetl. 13. Between each pair of flanges 10 o n the shaft 12 is mounted a brake member 14 which is' provided with an opening 15 adapted to re ceive the Vend of the shaft, the wall'of the said opening heilig serrated so as to engage Awith the teeth lon the shaft and thereby lock the brake member to the shaft. The shaft 12 g is mounted in the flanges 10 so as to be capablc of both a rotary and longitudinal movement and the-arrange1nent of the teeth on each end of the shaft is such that by shifting the Shaft longitudinally in either direction the smooth port-ion of the shaft will extend through the opening in one of the brake members sothatif the shaft is rotated it ,will not cause any movement of the said brake member, the object. of which will appear later. Toeach vof the bracket members 8 is secured a spring` 15. thc free end of which extends out under the adjacent brake member when the brakemember is in its normal or up position and serves not only to hold the brake member steady and prevent the rattling of the same but also serves' as a. cushioning means to absorb a portion of the jar when'the brake members are swungr down into their operative position and in contact with the ground. ln order to further absorb the shock consequent upoii the operation of the brake member a plate 1G is rigidly lcured to ea cli'brake member and these plates are so loca ted that when the brake members are thrown down 'by the rotation of the A brake shaft Vinto their operative position the said plates will crmcin contact with'the supporting springs under the rear portion of the body 2 and the resiliency of the springs` will tend to nullify the shock oc-l casionef` by 4the brake members comingin' contact with-the ground so that the machine will stop without causing any excessive jar to the machinery. In the lower end of each brake member 14 aremounted a plurality of' spikes' 22 which are arranged tdpenetrate the ground when the brake member is swung down into its operative position. A These spikes are held in place by a plate 23 which is secured to the brake member by bolts 24.

The object of this arrangement is to enable the spikes to be readily removed when they become worn down or broken.` To one end of the shaft l2, which supports the brake members 14, is secured a small arm 25 and this arm is operatively connected by a brake 10d 26 with the usual brake lever 27 which is pivotally supported on the body of the vehicle. l

The operation of my device is as follows The device is designed primarily to be used as a. brake only in cases of emergency when it becomes necessary to stop the Vvehicle in a very short space, in which case the operator by moving the brake lever rearwardly in the usual manner will cause a rotation of the shaft 12 which will swing down the brake members 14 in Contact with the surface over which the vehicle is traveling, and after the brake members are4 in engagement therewith the continued movement of the vehicle will cause the rear portion of the Vehicle to rise upon the brake members `as pivots so that the rear wheels will be entirely lifted from the surface on which the vehicle is 'traveling and the ,brake 1 members will then extend rearwardly and the plates 16 thereon will be in engagement with the springs 3 on the rear of the body portion. Now, when it is desired to use the device asa jack, if it is necessary to lift the entire rear of the machine the car is-started and the brake is 'then thrown down and the motion thereof will cause the rear portion of the car to ride up on the brake members and the rear wheels will then be lifted oil of the ground as before described. If it is desired to simply jack up one wheel the shaft 12 is shifted longitudinally by giving the end of the snaft a sharp rap with any convenient tool .or the heel of a shoe, so that the teeth on the shaft 12 atthe side of the machine7 which it is not desired to lift, will ho disengaged 'from the brake member at that side, but the brake member on the side which is to be lifted will be still engaged by theslmft. The brake lever is then operated and the brake member on the side which is to be lifted will be swung down and when the car is started it will ride up on the brake member which has been swung down, and the wheel at the side of the car adjacent to the brake member which has,

been 'swu'ng down will be lifted oil' the ground, but the wheel yon the opposite side will remain on the ground so that in order to reset thebrake it will only be necessary to back the car.

What I claimiisf- 1. The combination with a vehicle body and springs arranged under ,the rear en'd thereof cfa pair of brackets secured to said vehicle body, a shaft rotatably supported by said brackets, brake members secured to said shaft and in their normal position adapted to extend longitudinally of the vehicle body and in their operative position adapted to extend downwardly into engagement with the surface over which the 've-- hicle is moving, means for rotating said shaft so as to swing theA brake 4members down into their operative ositions'anda plate mounted on each bra. te member and adapted to come in contact with the supporting springs on .the rear of the vehicle body, for the purpose set forth.

2. 'The combination with a vehicle body of a pair of bracketsk secured to said vehicleV body, each bracket being provided with a. pair of downwardly extending Iianges provided with bearing openings, a shaft serrated at each end journaled in said flanges, a brake member mounted on said shaft between the flanges of each bracket member, said brake member having a serrated opening to receive the said shaft and meansl for rotating said shaft so as to bring the free ends-afb the brake 'members in contact with the surface over which the vehicle is moving. I

In testimony whereof, I sign the foregoing specification, in the presence of two witnesses.
